Senior Engineer I-II | Core Workflow Engine | Remote | Europe

Senior Engineer I-II | Core Workflow Engine | Remote | Europe The AI orchestration of your wildest imagination. n8n is the open workflow orchestration platform built for the new era of AI. We give technical teams the freedom of code with the speed of no-code, so they can automate faster, smarter, and without limits. Backed by a fiercely inventive community and 500+ builder-approved integrations, we’re changing the way people bring systems together and scale ideas for impact. Since our founding in 2019, we’ve grown into a diverse team of over 220 - working across Europe and the US, connected by a shared builder spirit and with our centre of gravity in Berlin. Along the way, we’ve: - Cultivated a community of more than 650,000 active developers and builders - Earned 145k+ GitHub stars, making us one of the world’s Top 40 most popular projects - Been ranked as one of Europe’s most promising privately held SaaS startups (4th in Sifted’s 2025 B2B SaaS Rising 100) - Raised $240m to date, from Sequoia’s first German seed to our recent $180m Series C - bringing us to a $2.5bn valuation That’s the company we’ve built. Now we’d love to see what you can build. If you’re applying, try n8n out - whether you’re technical or not - and share a screenshot of your first workflow with us. The easiest place to start is here: app.n8n.cloud/register http://app.n8n.cloud/register. We’re in a defining moment of an incredible journey. Come and build with us. 🎯 Your main goal will be to build and evolve core platform foundations that power n8n’s workflow engine and frontend platform, enabling product engineers (and the open-source community) to ship confidently across cloud and self-hosted deployments. As part of the team, you'll contribute to core platform domains and help improve reliability, scalability, and performance: BACKEND PLATFORM FOUNDATIONS (EXECUTION, ORCHESTRATION, DATA) - Contribute to backend subsystems like durable workflow execution & state, orchestration patterns, queue/task distribution, and system modularization. - Apply best practices for correctness and resilience (e.g., failure modes, idempotency, state handling) in systems that operate across cloud and self-hosted environments. - Improve data architecture and database performance, reliability, and maintainability. FRONTEND PLATFORM FOUNDATIONS (CANVAS, COLLABORATION, PERFORMANCE) - Work on the core canvas architecture and frontend platform primitives that enable complex workflow building experiences. - Build and improve real-time collaboration capabilities (e.g., WebSockets, CRDT-style approaches) with a focus on correctness and user experience. - Contribute to performance and rendering improvements (e.g., web workers, rendering optimization), and help strengthen platform contracts (plugin system, FE DX). TECHNICAL CONTRIBUTION & COLLABORATION - Contribute to technical decisions through clear proposals (e.g., RFCs) and discussions. - Collaborate with other teams to ensure platform changes integrate smoothly. - Support peers through code reviews, pairing, and knowledge sharing. REQUIREMENTS MUST-HAVES - 🧠 Systems thinking mindset: You think about correctness, trade-offs, and reliability — and enjoy working on foundational platform problems. - 🏗️ System design experience: You’ve contributed to system design decisions or worked on significant components, and can explain your technical choices clearly. - 🛠️ TypeScript depth: You have strong TypeScript experience and you’re comfortable working in a large, evolving codebase. - 🤝 Collaboration: You communicate well, work cross-functionally, and collaborate effectively with other engineers. - 🧹 Pragmatic engineering: You’re comfortable improving and refactoring existing systems to make them more scalable and maintainable. FOR BACKEND-FOCUSED CANDIDATES: - 🧩 Node.js backend systems: You’ve built backend systems in TypeScript/Node.js beyond CRUD. - 🌐 Distributed systems: You understand event-drive ...
